2. In the Display settings window, locate the “Resolution” dropdown menu.
3. Select a different resolution setting and click on “Apply” to see if it resolves the issue. If not, try another option.
4. If none of the resolutions fix the flashing problem, click on “Advanced display settings.”
5. In the Advanced display settings window, click on “Display adapter properties for Display X,” where X represents the monitor number if you have multiple monitors.
6. In the Adapter tab, click on “List All Modes” button.
7. Choose a different refresh rate from the list and click “OK.”

If adjusting the screen resolution and refresh rate does not resolve the flashing issue, proceed to troubleshoot the next possible cause.

Outdated Or Incompatible Drivers: Update Graphics Drivers

Outdated or incompatible graphics drivers can often be a cause of a Samsung monitor flashing on and off. Graphics drivers act as an interface between the operating system and the monitor, and when they are not up to date or incompatible with the monitor, it can result in flashing issues.

To resolve this problem, updating the graphics drivers is essential. First, determine the graphics card model installed on the computer. This information can usually be found in the device manager or by checking the manufacturer’s website.

Once the graphics card model is known, visit the manufacturer’s website to download the latest drivers for the specific model. Follow the instructions provided by the manufacturer to install the drivers correctly. It is also recommended to uninstall the previous drivers before installing the new ones.

After updating the drivers, restart the computer and check if the flashing issue persists. In most cases, updating the graphics drivers should resolve the problem. However, if the issue continues, further troubleshooting may be required to pinpoint the exact cause of the flashing.

Overheating And Ventilation: Monitor Temperature And Ensure Proper Airflow

Overheating can be a common cause for a Samsung monitor to flash on and off. When a monitor overheats, it can lead to various issues, including flickering or flashing. To address this problem, it is important to monitor the temperature of the monitor and ensure proper airflow around it.

Firstly, check if the monitor is placed in a well-ventilated area. Ensure that there is enough space around the monitor for hot air to dissipate properly. Remove any objects that may be blocking the airflow.

Secondly, verify if the monitor’s fans are working correctly. Most monitors have built-in fans to help keep the components cool. If the fans are not functioning properly, the monitor may overheat. Clean any dust or debris from the fan vents and make sure the fans are spinning freely.

Additionally, you can use external cooling methods such as placing a fan near the monitor or using a laptop cooling pad to further enhance airflow.

By monitoring the temperature, ensuring proper airflow, and maintaining the fans, you can effectively prevent overheating issues that may cause your Samsung monitor to flash on and off.
